The Gateway program has selected a Near-Rectilinear Halo Orbit (NRHO) of the L2
southern family as its operational orbit. In order to facilitate mission analysis for Gateway and …

In this paper, we investigate the manifolds of three Near-Rectilinear Halo Orbits (NRHOs)
and optimal low-thrust transfer trajectories using a high-fidelity dynamical model. Time-and …

NASA's Artemis program will return astronauts to the lunar surface using a Human Landing
System staged at Gateway's 9: 2 L2 southern NRHO. The current study explores global lunar …

NASA has committed to returning to the moon, landing the first woman and the next man on
its surface. To support a sustained lunar presence, NASA will assemble an orbital platform in …

The world is in the midst of what is widely considered the second Space Age due to the
vastly growing commercial space sector and progress with international initiatives such as …

The world is arguably in the beginning of the second Space Age. The continued
development and support of NASA's Artemis program and similar international efforts has …

Gateway represents a key element of the Artemis program for the upcoming lunar
exploration aimed at establishing a sustainable presence by the mid-2030s. This paper …

The growing interest in cislunar space exploration in recent years has driven an increasing
demand for efficient low-thrust missions to key cislunar orbits. These missions, typically …

Many future satellite applications in cislunar space require repeating, periodic transfers that
shift away from some operational orbit and eventually return. Resonant orbits are …

In recent times, as the National Aeronautics and Space Administration (NASA) focuses on
establishing a sustained presence in cislunar space, there has been an increase in planned …
